Polymerization of olefins
A process is described precipitating a product in the presence of a particular diluent. The diluent comprises polyolefin fibrils suspended in a solution of metal halide compound and transition metal compound. The metal halide compound comprises a metal dihalide or metal hydroxyhalide. The metal of the metal halide compound is selected from the group consisting of Group IIA and Group IIB metals and the transition metal compound contains a transition metal compound selected from Group IVB and VB. The transition metal is bonded to at least one atom selected from the group consisting of oxygen, nitrogen and sulfur. The oxygen, nitrogen and sulfur atoms are in turn bonded to a hydrocarbyl group containing from 1 to about 20 carbon atoms. A process further comprising polymerizing an effective amount of an alpha-olefin onto the catalyst to form an improved catalyst is also described.
